Top woman Eleanor Jamieson also impressed by gaining a few positions in Guernsey Athletics’ all-time 10km rankings after an event featuring 359 finishers and which, though not presented as a race, tends to attract a contingent of club competitors.
In the case of Rees, who had less than 72 hours earlier produced a record run in favourable winds at the Vazon Mile, he defied persistent easterlies on the Portelet to Grandes Rocques course and posting a swift 31min. 50sec.
It marked the 19-year-old’s second quickest time yet for the distance, following on from his 31-02 victory at the Eastleigh 10km in March, and is still faster than any other Guernsey athlete this season.
Some other isolated runners had suffered more clearly from the conditions, including Rick Weston not spending any significant time in his slipstream and settling for a more distant second than could be expected in 33-54.
A good race for third had developed behind them, with Mikey Ingrouille vying with veterans Matt Jamieson and Andrew Zabiela throughout the race.
GAC endurance captain Ingrouille finished strongly to complete the podium positions in 35-33, leading Jamieson by 5sec. and Zabiela by 9sec.
George Nichols tackled the wind solo most of the way, but he still finished a strong sixth in 36-21.
Finishing ninth overall and top woman, 18-year-old Jamieson continued her breakthrough season that had included victory on the same course in June.
She also managed a significant personal best of 37-20 to go eighth on the Guernsey women’s all-time list. It was enough for a dominant victory from the resurgent Sarah Roe (39-25) and Ulrike Maisch (39-46).
Jamieson had the company of one small group in the early stages, ahead of another bunch that included veteran rival Maisch.
She dropped off her initial group but had been encouraged to stick with the next by Guernsey Athletics endurance stalwart Danny Blake, who before long – coming off the water station positioned at half-way – joined her in dropping that bunch, with the duo working together from there to tame the wind.
Roe came through for second, backing up her victory in the Summer Full Course earlier this month.
